Continuous process for highly overbased petroleum sulfonates using a series of stirred tank reactors

A method and apparatus for the continuous overbasing of petroleum sulfonate in which there is a seriatim contacting at reaction conditions in a series of at least four stirred reaction zones of CO2 with a feedstock mixture in the first reaction zone containing (1) petroleum sulfonate, (2) 100 neutra...

Zusammenfassung:	A method and apparatus for the continuous overbasing of petroleum sulfonate in which there is a seriatim contacting at reaction conditions in a series of at least four stirred reaction zones of CO2 with a feedstock mixture in the first reaction zone containing (1) petroleum sulfonate, (2) 100 neutral lube oil, (3) Ca(OH)2, (4) methanol, and (5) naphtha and a feedstock mixture in each successive reaction zone that is the effluent from the last previous reaction zone. Method and apparatus for the recovery of a dispersion of CaCO3 in a mixture of calcium petroleum sulfonate and 100 neutral lube oil stock as product from the last reaction zone effluent.
